Urine The composition of urine varies enormously in different animals and at different times in the same animal. This is because the blood from which the urinary excretion is obtained by the kidneys is such a kaleidoscopic modifiable fluid tissue that it reflects constantly different states of metabol- ism within the body. Furthermore, under pathological conditions still other variations from the normal in the composition of the urine appear. Con- sequently urine analysis is an important aid to the diagnostician in finding out what is going on within the body. This fact was realized even by the.
